TOOL FOR STOVE PIPES.

SPECIFICATION forming part of Letters Patent No. 554,982, dated February 18, 1896. Application filed July 16,1895. Seria1No.656,107. (No model.)

To aZZ whom it may concern:

Be it known that I, ALBERT B. CLAFLIN, of Staples, in the county of Todd and State of Minnesota, have invented a' new and l1nproved Tool for Stovepipes, of which the following is a full, clear, and exact description.

The object of this invention is to provide a tool which may be used to advantage by persons engaged in setting up stoves and stovepipes, and which will comprise a device for cutting the pipes into the desired lengths, and also for crimping the edges thereof so that they may be reduced in size, as is necessary in fitting their ends one within the other.

To this end my invention comprises substantiallya body or handle portion having at one end a peculiarly constructed and arranged cutting device, and having at the other end a series of intermeshing wheels, between which the edges of the pipe may be passed and by which the crimping may be efiected.

The invention will be more fully described hereinafter and the novelty thereof embodied in the claims.

Reference is to be had to the accompanying drawings, forminga part of this specification,

in which similar characters of reference indi-' cate corresponding partsin all the figures.

Figure 1 represents a side elevation of a tool embodying the essential features of my invention. Fig. 2 is an end elevation thereof, parts being shown. in section. Fig. 3 is a detail section on the line 3 3 of Fig. 1, and Fig. 4 is a sectional view on the line 4 4 of the same figure.

In a tool constructed after the manner of my invention a handle or body portion a is provided, and this handle part has a tapering shape and the smaller end thereof is curved laterallyto form a fulcrum-point b. Rigidly secured to the under side of the handle a by means of a stud c projecting through the handle is a knife d, which is disposed with its edge adjacent to the handle I) and curved outwardly, as best shown in Fig. 2 of the drawings. This knife is centrally located in rela tion to the handle and co-operates with the fulcrum-point b, as will be better explained hereinafter. The knife d is provided with a shank e, which is adapted to bear against the handle a and lend rigidity to the fastening of the knife.

The opposite or larger end of the handle a is .provided with two forked or bifurcated arms f, and these arms are arranged in transverse alignment with each other and have the pins g respectively fixed therein. The pins g are provided with wheels h and 2', the same being respectively mounted to rotate on the pins, and the wheel h is formed with two duplicate and peripheral ribs which have convex outer faces and which are arranged to fit snugly within the respective peripheral and curved grooves of the wheel i, so that the wheels are made capable of forming a crimp 6 5 or corrugation in the sheet metal which may be passed between them.

In the use of my invention, and supposing that it is desired to cut a stovepipe with the same, all that will be necessary is to project the point of the knife (:1 through the stovepipe and to permit the fulcrum-point b to bear upon the outer side thereof, the cutting being effected by rocking the handle a on the fulcrum-point b,so as to cause the knife d to move in substantially a curved line through the metal composing the pipe.

Supposing that it is desired to corrugate or crimp the edge of the pipe, all that will be necessary is to grasp the handle aand to move the tool so that the pipe will be caused to pass between the wheels h and 2', and this operation will form two crimps or corrugations in the pipe. After the first two have been formed the operation should be repeated until the entire edge is properly crimped.

. Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A tool, comprising a handle having two forked or bifurcated arms, and crimpingwhecls respectively j ournaled in said arms, substantially as described.

2. A tool, for stovepipes, comprising a handle having one end bent laterally to form a 95 fulcrum-point, a knife fixed to the handle and adjacent to said fulcrum-point, and two crimping-wheels revolubly mounted at the opposite end of the handle, substantially as with each other in their operation, suhstandescribed. tially as described.

A tool for stovepipes, the same colnpris- AT BFRT B CI AFT IN ing a flattened handle, a knife secured to one J J J side of the handle and adjacent to one of its Witnesses: ends, and two crimping-wheels mounted at W. 0. MILES, the opposite end of the handle and coacting O. F. HALL.
